2016-10-19journal: cache used vfs stats as wellFranck Bui
The set of storage space values we cache are calculated according to a couple of filesystem statistics (free blocks, block size). This patch caches the vfs stats we're interested in so these values are available later and coherent with the rest of the space cached values.
2016-10-19journal: don't emit space usage message when opening the journal (#4190)Franck Bui
This patch makes system_journal_open() stop emitting the space usage message. The caller is now free to emit this message when appropriate. When restarting the journal, we can now emit the message *after* flushing the journal (if required) so that all flushed log entries are written in the persistent journal *before* the status message. This is required since the status message is always younger than the flushed entries. Fixes #4190.
2016-10-19journal: introduce server_space_usage_message()Franck Bui
This commit simply extracts from determine_space_for() the code which emits the storage usage message and put it into a function of its own so it can be reused by others paths later. No functional changes.
2016-10-19journal: introduce JournalStorage and JournalStorageSpace structuresFranck Bui
This structure keeps track of specificities for a given journal type (persistent or volatile) such as metrics, name, etc... The cached space values are now moved in this structure so that each journal has its own set of cached values. Previously only one set existed and we didn't know if the cached values were for the runtime journal or the persistent one. When doing: determine_space_for(s, runtime_metrics, ...); determine_space_for(s, system_metrics, ...); the second call returned the cached values for the runtime metrics.
2016-10-19journal: introduce determine_path_usage()Franck Bui
This commit simply extracts from determine_space_for() the code which determines the FS usage where the passed path lives (statvfs(3)) and put it into a function of its own so it can be reused by others paths later. No functional changes.
2016-10-17pid1: do not use mtime==0 as sign of masking (#4388)Zbigniew Jędrzejewski-Szmek
It is allowed for unit files to have an mtime==0, so instead of assuming that any file that had mtime==0 was masked, use the load_state to filter masked units. Fixes https://bugzilla.redhat.com/show_bug.cgi?id=1384150.
2016-10-16tree-wide: introduce free_and_replace helperZbigniew Jędrzejewski-Szmek
It's a common pattern, so add a helper for it. A macro is necessary because a function that takes a pointer to a pointer would be type specific, similarly to cleanup functions. Seems better to use a macro.

2016-10-14core: make settings for unified cgroup hierarchy supersede the ones for ↵Tejun Heo
legacy hierarchy (#4269) There are overlapping control group resource settings for the unified and legacy hierarchies. To help transition, the settings are translated back and forth. When both versions of a given setting are present, the one matching the cgroup hierarchy type in use is used. Unfortunately, this is more confusing to use and document than necessary because there is no clear static precedence. Update the translation logic so that the settings for the unified hierarchy are always preferred. systemd.resource-control man page is updated to reflect the change and reorganized so that the deprecated settings are at the end in its own section.

Fixes: #4060
2016-10-12journalctl: don't claim the journal was stored on diskLennart Poettering
Let's just say that the journal takes up space in the file system, not on disk, as tmpfs is definitely a file system, but not a disk. Fixes: #4059
2016-10-12journal: refuse opening journal files from the future for writingLennart Poettering
Never permit that we write to journal files that have newer timestamps than our local wallclock has. If we'd accept that, then the entries in the file might end up not being ordered strictly. Let's refuse this with ETXTBSY, and then immediately rotate to use a new file, so that each file remains strictly ordered also be wallclock internally.
2016-10-12journald: automatically rotate journal files when the clock jumps backwardsLennart Poettering
As soon as we notice that the clock jumps backwards, rotate journal files. This is beneficial, as this makes sure that the entries in journal files remain strictly ordered internally, and thus the bisection algorithm applied on it is not confused. This should help avoiding borked wallclock-based bisection on journal files as witnessed in #4278.
2016-10-12journald: use the event loop dispatch timestamp for journal entriesLennart Poettering
Let's use the earliest linearized event timestamp for journal entries we have: the event dispatch timestamp from the event loop, instead of requerying the timestamp at the time of writing. This makes the time a bit more accurate, allows us to query the kernel time one time less per event loop, and also makes sure we always use the same timestamp for both attempts to write an entry to a journal file.
2016-10-12journal: when iterating through entry arrays and we hit an invalid one keep ↵Lennart Poettering
going When iterating through partially synced journal files we need to be prepared for hitting with invalid entries (specifically: non-initialized). Instead of generated an error and giving up, let's simply try to preceed with the next one that is valid (and debug log about this). This reworks the logic introduced with caeab8f626e709569cc492b75eb7e119076059e7 to iteration in both directions, and tries to look for valid entries located after the invalid one. It also extends the behaviour to both iterating through the global entry array and per-data object entry arrays. Fixes: #4088
2016-10-12journal: add an explicit check for uninitialized objectsLennart Poettering
Let's make dissecting of borked journal files more expressive: if we encounter an object whose first 8 bytes are all zeroes, then let's assume the object was simply never initialized, and say so. Previously, this would be detected as "overly short object", which is true too in a away, but it's a lot more helpful printing different debug options for the case where the size is not initialized at all and where the size is initialized to some bogus value. No function behaviour change, only a different log messages for both cases.
2016-10-12journal: also check that our entry arrays are properly orderedLennart Poettering
Let's and extra check, reusing check_properly_ordered() also for journal_file_next_entry_for_data().
2016-10-12journal: split out check for properly ordered arrays into its own functionLennart Poettering
This adds a new call check_properly_ordered(), which we can reuse later, and makes the code a bit more readable.
2016-10-12journal: split out array index inc/dec code into a new call bump_array_index()Lennart Poettering
This allows us to share a bit more code between journal_file_next_entry() and journal_file_next_entry_for_data().
2016-10-12journal: when we encounter a broken journal file, add some debug loggingLennart Poettering
Let's make it easier to figure out when we see an invalid journal file, why we consider it invalid, and add some minimal debug logging for it. This log output is normally not seen (after all, this all is library code), unless debug logging is exlicitly turned on.
2016-10-12Avoid forever loop for journalctl --list-boots command (#4278)hese10
When date is changed in system to future and normal user logs to new journal file, and then date is changed back to present time, the "journalctl --list-boot" command goes to forever loop. This commit tries to fix this problem by checking first the boot id list if the found boot id was already in that list. If it is found, then stopping the boot id find loop.

2016-10-12core:sandbox: lets make /lib/modules/ inaccessible on ProtectKernelModules=Djalal Harouni
Lets go further and make /lib/modules/ inaccessible for services that do not have business with modules, this is a minor improvment but it may help on setups with custom modules and they are limited... in regard of kernel auto-load feature. This change introduce NameSpaceInfo struct which we may embed later inside ExecContext but for now lets just reduce the argument number to setup_namespace() and merge ProtectKernelModules feature.

2016-10-12core:sandbox: Add ProtectKernelModules= optionDjalal Harouni
This is useful to turn off explicit module load and unload operations on modular kernels. This option removes CAP_SYS_MODULE from the capability bounding set for the unit, and installs a system call filter to block module system calls. This option will not prevent the kernel from loading modules using the module auto-load feature which is a system wide operation.

2016-10-12Allow block and char classes in DeviceAllow bus properties (#4353)Zbigniew Jędrzejewski-Szmek
Allowed paths are unified betwen the configuration file parses and the bus property checker. The biggest change is that the bus code now allows "block-" and "char-" classes. In addition, path_startswith("/dev") was used in the bus code, and startswith("/dev") was used in the config file code. It seems reasonable to use path_startswith() which allows a slightly broader class of strings. Fixes #3935.

2016-10-11core/main: get rid from excess check of ACTION_TEST (#4350)0xAX
If `--test` command line option was passed, the systemd set skip_setup to true during bootup. But after this we check again that arg_action is test or help and opens pager depends on result. We should skip setup in a case when `--test` is passed, but it is also safe to set skip_setup in a case of `--help`. So let's remove first check and move skip_setup = true to the second check.
